Hi,

Can anyone confirm if mac80211 rate control algorithm supports HE rates ?=20

The rate control code and rate control flags (below) received in Tx command=
 only seem to handle HT and VHT ?=20

We took a look at the ath11k driver but it does not seem to be extracting a=
ny rates for the Tx command unlike ath9k.

enum mac80211_rate_control_flags {
        IEEE80211_TX_RC_USE_RTS_CTS             =3D BIT(0),
        IEEE80211_TX_RC_USE_CTS_PROTECT         =3D BIT(1),
        IEEE80211_TX_RC_USE_SHORT_PREAMBLE      =3D BIT(2),

        /* rate index is an HT/VHT MCS instead of an index */
        IEEE80211_TX_RC_MCS                     =3D BIT(3),
        IEEE80211_TX_RC_GREEN_FIELD             =3D BIT(4),
        IEEE80211_TX_RC_40_MHZ_WIDTH            =3D BIT(5),
        IEEE80211_TX_RC_DUP_DATA                =3D BIT(6),
        IEEE80211_TX_RC_SHORT_GI                =3D BIT(7),
        IEEE80211_TX_RC_VHT_MCS                 =3D BIT(8),
        IEEE80211_TX_RC_80_MHZ_WIDTH            =3D BIT(9),
        IEEE80211_TX_RC_160_MHZ_WIDTH           =3D BIT(10),
};
